6882-415: The planes that the USAF planned to buy in the future were to be unmanned. According to Air Force Chief Scientist, Greg Zacharias , the USAF anticipates having hypersonic weapons by the 2020s, hypersonic unmanned aerial vehicles (also known as remotely-piloted vehicles, or RPAs) by the 2030s and recoverable hypersonic RPAs aircraft by the 2040s. The USAF intends to deploy a Sixth-generation jet fighter by

6975-546: The potential consequences of an accident or unauthorized act, nuclear weapons and nuclear weapon systems require special consideration and protection against risks and threats inherent in their peacetime and wartime environments. In conjunction with other entities within the Departments of Defense or Energy, the Air Force achieves a high standard of protection through a stringent nuclear surety program. This program applies to materiel, personnel, and procedures that contribute to

7068-494: The president of MIT, was not eager for MIT to become involved in air defense. He asked the United States Air Force if MIT could first conduct a study to evaluate the need for a new laboratory and to determine its scope. Killian's proposal was approved, and a study named Project Charles (for the Charles River that flows past MIT) was carried out between February and August 1951. The final Project Charles report stated that

7161-483: The production of intelligence" (JP 2-01). It provides the ability to transform, extract, and make available collected information suitable for further analysis or action across the ROMO. Analysis and production is "the conversion of processed information into intelligence through the integration, evaluation, analysis, and interpretation of all source data and the preparation of intelligence products in support of known or anticipated user requirements" (JP 2-01). It provides

7254-686: The professional staff hold advanced degrees, and 60% of those degrees are at the doctoral level. The technical work is organized into eight divisions: Air, Missile, & Maritime Defense Technology, Homeland Protection and Air Traffic Control, Cyber Security and Information Sciences, Communication Systems, Engineering, Advanced Technology, Space Systems and Technology, and ISR and Tactical Systems. Lincoln Laboratory supports its research and development work with an infrastructure of services from six departments: Contracting Services, Facility Services, Financial Services, Information Services, Security Services, and Human Resources. Approximately 1300 people working in

7347-491: The safe, efficient, and flexible use of airspace, mitigates the risk of fratricide, enhances both offensive and defensive operations, and permits greater agility of air operations as a whole. It both deconflicts and facilitates the integration of joint air operations. Global integrated intelligence, surveillance, and reconnaissance (ISR) is the synchronization and integration of the planning and operation of sensors, assets, and processing, exploitation, dissemination systems across

7440-602: The safety, security, and control of nuclear weapons, thus assuring no nuclear accidents, incidents, loss, or unauthorized or accidental use (a Broken Arrow incident ). The Air Force continues to pursue safe, secure and effective nuclear weapons consistent with operational requirements. Adversaries, allies, and the American people must be highly confident of the Air Force's ability to secure nuclear weapons from accidents, theft, loss, and accidental or unauthorized use. This day-to-day commitment to precise and reliable nuclear operations

7533-663: The service departments or as technical specialists support the research and development mission of the laboratory. Lincoln Laboratory supports several community outreach programs. Programs that promote education in science, technology, engineering, and mathematics for students in grades kindergarten to high school are offered to the local community and are supported by volunteers from across the laboratory. The Lincoln Laboratory community service program raises awareness of both local and national needs by organizing fund-raising and outreach events that support selected charitable organizations, medical research, and U.S. troops abroad. Since 1995,

7626-558: The sound barrier in his X-1 rocket-powered aircraft, beginning a new era of aeronautics in America. The predecessor organizations in the Army of today's Air Force are: During the early 2000s, two USAF aircraft procurement projects took longer than expected, the KC-X and F-35 programs. As a result, the USAF was setting new records for average aircraft age. Since 2005, the USAF has placed

7719-664: The system. However, the Whirlwind was not reliable or fast enough for the processing needed for analyzing data coming in from dozens of, perhaps even 100, radars. Jay Wright Forrester , an MIT professor instrumental in the development of the Whirlwind, found the breakthrough to enable the computer to achieve outstanding reliability and doubled speed — the magnetic-core memory . The magnetic-core memory revolutionized computing. Computers became machines that were not just large and fast calculators; their uses for varying applications grew. Industry followed this development closely, adopting

7812-501: The three military departments of the Department of Defense . The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force , who reports to the Secretary of Defense and is appointed by the President with Senate confirmation . The highest-ranking military officer in the Air Force is the Chief of Staff of the Air Force , who exercises supervision over Air Force units and serves as one of

7905-467: The war, with only the infantry suffering more casualties. In practice, the U.S. Army Air Forces ( USAAF ) was virtually independent of the Army during World War II, and in virtually every way functioned as an independent service branch, but airmen still pressed for formal independence. The National Security Act of 1947 was signed on 26 July 1947, which established the Department of the Air Force , but it

7998-505: Was completed (and obsolete) in 1963, and a system ergonomic test was performed at Luke Air Force Base in 1964. According to Harold Sackman, it "showed conclusively that the wrong timing of human and technical operations was leading to frequent truncation of the flight path tracking system." Back-Up Interceptor Control Systems (BUIC) were used to replace the AN/FSQ-7s: two remained at SAGE sites until 1983 including McChord AFB, and

8091-573: Was completed in 1955, equipped with a prototype AN/FSQ-7 known as XD-1 in Building F. The third evaluation run with the XD-1 was in August and the prototype was complete in October 1955, except for displays. DC-1 at McGuire Air Force Base was the first operational site of the AN/FSQ-7 with consoles scheduled for delivery Aug–Oct 1956. Groundbreaking at McChord Air Force Base was in 1957 where

8184-500: Was not until 18 September 1947, when the first secretary of the Air Force, W. Stuart Symington , was sworn into office that the Air Force was officially formed as an independent service branch. The act created the National Military Establishment (renamed Department of Defense in 1949), which was composed of three subordinate Military Departments, namely the Department of the Army , the Department of

8277-429: Was that he had repeatedly clashed with Wynne and Moseley over other important non-nuclear related issues to the service. This followed an investigation into two incidents involving mishandling of nuclear weapons : specifically a nuclear weapons incident aboard a B-52 flight between Minot AFB and Barksdale AFB , and an accidental shipment of nuclear weapons components to Taiwan. To put more emphasis on nuclear assets,

8370-449: Was the development of magnetic-core memory that vastly improved reliability, doubled operating speed, and quadrupled input speed relative to the original Williams tube memory of the Whirlwind I. The AN/FSQ-7 was based on the larger and faster (but uncompleted) Whirlwind II design. It proved too much for MIT's resources, resulting in IBM being retained as prime contractor – though

8463-530: Was the first officer appointed to that position who did not have a background as a fighter or bomber pilot. The Washington Post reported in 2010 that General Schwartz began to dismantle the rigid class system of the USAF, particularly in the officer corps. In 2014, following morale and testing/cheating scandals in the Air Force's missile launch officer community, Secretary of the Air Force Deborah Lee James admitted that there remained

8556-516: Was transferred to and from the core memory as binary images . Only the rightmost 64 columns were transferred, with each row containing two 32-bit words. (The left columns could be punched using a special instruction.) Data were transferred to the line printer as a card image as well. The FSQ-7 and -8 used core memory with 32-bit words plus a parity bit, operating at a 6-microsecond cycle time. Both machines had two banks of memory, memory 1 and memory 2 (Commonly referred to as Big Mem and little Mem). On

8649-522: Was unprepared for the threat of an air attack. Because of MIT's management of the Radiation Laboratory during World War II , the experience of some of its staff on the Air Defense Systems Engineering Committee, and its proven competence in advanced electronics, the Air Force suggested that MIT could provide the research needed to develop an air defense that could detect, identify, and ultimately intercept air threats.
